Description

TECHNICAL FIELD

[0001] The utility model relates to an improved invention of exhaust film bag processing equipment, especially to an exhaust film bag anti-adhesion processing mechanism. BACKGROUND

[0002] The granular and powdery products in food, building material, chemical industry and other industries are mainly packaged by filling, and the packaging bag of this kind of packaging should have both sealing property and exhaust function. Exhaust is to discharge the gas in the bag after filling, so as to facilitate the stacking, transportation and sale of the packaging bag after filling. If there is gas in the bag, it is not conducive to the stacking and transportation of the product, and the packaging bag is prone to rupture under pressure.

[0003] The sealed bag with exhaust function has an exhaust passage. If the bag surfaces of the exhaust passage are mutually adhered, the exhaust passage is blocked, and the gas in the bag is accumulated and cannot be smoothly discharged. SUMMARY

[0004] In view of the technical problems in the background art, the technical problem solved by the utility model is to provide an exhaust film bag anti-adhesion processing mechanism.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: the exhaust film bag anti-adhesion processing mechanism, characterized by comprising a pressure roller, an embossing wheel set and a cross beam,

[0006] The pressure roller is rotationally arranged on the rack;

[0007] The pressure wheel set comprises a support, an embossing wheel and a first driving member for driving the embossing wheel to lift, the embossing wheel is rotationally arranged on the support, and the surface of the embossing wheel is uniformly distributed with protrusions;

[0008] The pressure wheel set is transversely slidably arranged on the cross beam, for adjusting the transverse position of the embossing wheel on the rack, and the cross beam is installed on the rack;

[0009] When the film embossing condition is met, the film passes between the embossing wheel and the pressure roller, the first driving member drives the embossing wheel to press against the pressure roller, and the protrusions for preventing adhesion are formed on the film.

[0010] In the film conveying process, the film passes through the embossing wheel and the pressure roller which are pressed together, so that the protrusions for preventing adhesion are formed on the surface of the film in a longitudinal and continuous manner. The protrusions isolate the two layers of film, avoid the complete adhesion of the two layers of film, and make the exhaust passage between the two layers of film unobstructed.

[0011] As a preferred, the cross beam is connected with a second driving member for driving it to move up and down on the rack, and the second driving member is installed on the rack;

[0012] When the film is threaded or the embossing wheel is replaced, the first driving member drives the embossing wheel away from the compression roller, and the second driving member drives the crossbeam away from the compression roller. Increasing the distance between the embossing wheel and the compression roller facilitates threading of the film and replacement of the embossing wheel, and avoids scratching or damaging the film due to the small distance between the embossing wheel and the compression roller.

[0013] Preferably, the crossbeam comprises an upper crossbeam and a lower crossbeam, and the compression wheel set comprises an upper compression wheel set and a lower compression wheel set. The upper compression wheel set is slidingly arranged on the upper crossbeam, and the lower compression wheel set is slidingly arranged on the lower crossbeam. The film is arranged around the compression roller. The arrangement of the upper and lower compression wheel sets increases the number of compression wheel sets. Since each embossing wheel is driven by an independent first driving member, the required position of the compression wheel set can be selected for operation according to the requirements, which facilitates operation.

[0014] Preferably, the upper crossbeam is provided with an upper sliding rail, and a plurality of upper sliding seats are slidingly arranged on the upper sliding rail. The upper sliding seats are locked on the upper sliding rail by locking bolts.

[0015] The first driving member of the upper compression wheel set is mounted on the upper sliding seat, and the bracket of the upper compression wheel set is connected with the first driving member.

[0016] The position of the upper compression wheel set is adjusted in the transverse direction according to requirements, and the locking bolt is locked after the adjustment is completed, which is simple and convenient to operate.

[0017] Preferably, the second driving member comprises a motor and an eccentric shaft. A transmission wheel is mounted on the output shaft of the motor and the eccentric shaft. A transmission belt is arranged on the transmission wheel.

[0018] Eccentric wheels are mounted at both ends of the eccentric shaft. A connecting rod is rotatably connected to the eccentric wheels. The connecting rod is rotatably connected to the eccentric wheels. The other end of the connecting rod is connected to the crossbeam. The crossbeam is slidingly arranged on the guide rail. The guide rail is vertically arranged on the rack. The motor drives the eccentric shaft to rotate, and the eccentric wheels rotate accordingly. The eccentric wheels drive the crossbeam to move up and down along the guide rail through the connecting rod. The mechanical transmission is more stable.

[0019] Preferably, a color mark sensor is arranged on the film conveying path. The first driving member and the color mark sensor are connected with the controller.

[0020] The controller sends instructions to the first driving member according to the color mark information collected by the color mark sensor on the film. The position of the embossing is accurately controlled, and the quality of the exhaust bag is improved.

[0021] Preferably, the first driving member has a buffering force when driving the embossing wheel to press against the compression roller; the first driving member is a pneumatic cylinder, and the compression roller is a rubber roller. The pneumatic cylinder has a certain buffering force when driving the embossing wheel to press against the compression roller, which ensures appropriate pressing force between the embossing wheel and the compression roller, so that the surface of the rolled film has protrusions; meanwhile, the buffering force avoids damage to the film caused by hard pressing force between the embossing wheel and the compression roller, and ensures rolling quality and rolling effect.

[0026] The following describes relevant details and working principles of the embodiments of the utility model in combination with the drawings. The exhaust film bag anti-adhesion processing mechanism comprises a compression roller 9, an embossing wheel set and cross beams 5 and 12, the compression roller is rotationally arranged on a rack 3; the embossing wheel set comprises a support 16, an embossing wheel 8 and a first driving member 7 for driving the embossing wheel to lift, the embossing wheel 8 is rotationally arranged on the support 16, the surface of the embossing wheel is uniformly distributed with protrusions, the embossing wheel set is transversely slidably arranged on the cross beam, and is used for adjusting the transverse position of the embossing wheel on the rack, the cross beam is installed on the rack 3, the embossing wheel set is transversely moved according to the width of the film 1 and the protrusion processing position, so that it corresponds to the processing position on the film 1 and the processing position is accurately processed; when the film is in the embossing condition, the film passes through between the embossing wheel 8 and the compression roller 9, the first driving member 7 drives the embossing wheel to press against the compression roller, and protrusions for anti-adhesion are formed on the film. Specifically, the exhaust film bag takes the film 1 as a base material, the film is rolled and pressed by the embossing wheel and the compression roller of the anti-adhesion station before the bag body is formed, and continuous anti-adhesion protrusions are formed on the film. The protrusions isolate the two layers of films of the exhaust passage of the formed exhaust bag, avoid complete adhesion of the two layers of films, and make the exhaust passage between the two layers of films unobstructed; if the film does not need to be processed by the anti-adhesion protrusions, the first driving member 7 drives the embossing wheel 8 to lift, the embossing wheel is separated from the compression roller, and the film only passes around the compression roller when passing through the anti-adhesion station, so that the film is not rolled and pressed by the embossing wheel and protrusions are not formed.

[0027] The first driving member 7 has a buffering force when driving the embossing wheel to press against the compression roller. For example, a spring is arranged between the embossing wheel and the compression roller, and the elastic force of the spring serves as a certain buffering force. Alternatively, the first driving member 7 is a pneumatic cylinder, and the pneumatic cylinder can be retracted when driving the embossing wheel to press against the compression roller, so that the pneumatic cylinder also has a certain buffering force. Preferably, the compression roller is a rubber roller. In this way, the embossing wheel and the compression roller are properly pressed against each other, so that the surface of the rolled film is provided with protrusions. At the same time, the film is prevented from being damaged due to the hard and excessive pressing force of the embossing wheel and the compression roller, and the rolling quality and effect are ensured.

[0028] The cross beam is connected with a second driving member that drives the cross beam to move up and down on the frame, and the second driving member is mounted on the frame. When the film is replaced or the embossing wheel is replaced, the first driving member drives the embossing wheel to move away from the compression roller, and the second driving member drives the cross beam to move away from the compression roller, so that the distance between the embossing wheel and the compression roller is doubled, and the film is easily replaced and the embossing wheel is easily replaced, and the film is prevented from being scratched or damaged due to the small distance between the embossing wheel and the compression roller. The cross beam includes an upper cross beam 5 and a lower cross beam 12, and the compression wheel set includes an upper compression wheel set and a lower compression wheel set 10. The upper compression wheel set is slidably arranged on the upper cross beam 5, and the lower compression wheel set 10 is slidably arranged on the lower cross beam 12. The film 1 is arranged around the compression roller. The upper and lower compression wheel sets increase the number of compression wheel sets. Since each embossing wheel is driven by an independent first driving member, the required position of the compression wheel set can be selected for operation according to the requirements, and the operation is facilitated. The upper cross beam 5 is provided with an upper sliding rail 6, and a plurality of upper sliding seats 17 are slidably arranged on the upper sliding rail. The upper sliding seats are locked on the upper sliding rail by locking bolts. The first driving member 7 of the upper compression wheel set is mounted on the upper sliding seat 17, and the bracket 16 of the upper compression wheel set is connected with the first driving member 7. The position of the upper compression wheel set is adjusted in the transverse direction according to the requirements, and the adjustment is locked by locking bolts after completion. The operation is simple and convenient. Similarly, the lower cross beam 12 is provided with a lower sliding rail 11, and a plurality of lower sliding seats are slidably arranged on the lower sliding rail. The lower sliding seats are locked on the lower sliding rail by locking bolts. The first driving member of the lower compression wheel set is mounted on the upper sliding seat, and the bracket of the lower compression wheel set is connected with the first driving member. In the drawings, the upper cross beam 5 is connected with the second driving member, and the lower cross beam is fixed on the frame. Of course, the lower cross beam can also have the function of lifting, so that the embossing wheel moves away from the compression roller when the film is replaced or the compression roller is replaced. The second driving member includes a motor 13 and an eccentric shaft 15. A transmission wheel is mounted on the output shaft of the motor and the eccentric shaft. A transmission belt 14 is arranged on the transmission wheel. Eccentric wheels 4 are mounted at both ends of the eccentric shaft. The eccentric wheels are rotatably connected with connecting rods. The connecting rods are rotatably connected with the eccentric wheels. The other ends of the connecting rods are connected with the cross beam 5. The cross beam is slidably arranged on a guide rail. The guide rail is vertically arranged on the frame. The motor 13 drives the eccentric shaft 15 to rotate through the transmission wheel and the transmission belt 14. The eccentric shaft drives the eccentric wheels 4 to rotate. The eccentric wheels drive the cross beam 5 to move up and down along the guide rail through the connecting rods. The mechanical transmission is more stable.

[0029] In order to accurately control the processing position of the protrusion on the film, a color mark sensor 2 is arranged on the film conveying path, and the first driving member 7 and the color mark sensor 2 are connected with the controller; the controller sends an instruction to the first driving member according to the color mark information collected by the color mark sensor on the film, and the first driving member drives the embossing wheel to be pressed with the compression roller or drives the embossing wheel to be lifted and separated from the compression roller, so as to accurately control the position of the film embossing and improve the quality of the exhaust bag.
